Boreas A70 & A90
The Boreas A70 and A90 Series is a rugged inertial navigation system with a north-seeking gyrocompass that maintains reliable navigation in GPS-denied and harsh environments and a lower SWaP-C (Size, Weight, Power and Cost).

The Boreas A Series provides north-seeking gyrocompassing for accurate heading and orientation, even in GNSS-denied environments. The A70 & A90 variant provides heading and orientation as an AHRS and INS. For position and navigation, the Boreas A Series can also offer full INS capabilities when provided with an external position source, such as an external GNSS receiver.

Features

FOG Technology
The Boreas fiber optic gyroscope (FOG) is a highly accurate and reliable navigation technology. It’s the result of over 25 years of development in partnership with two research institutions. The gyroscope uses a closed-loop optical coil and an advanced spread-spectrum digital modulation technique to improve accuracy, stability, and reliability while reducing size, weight, power, and cost.

Gyrocompass North-Seeking
The Boreas range of FOGs can determine heading without needing a Global Navigation Satellite System (GNSS) or a magnetometer. By sensing the Earth’s rotation, the system’s north-seeking algorithm can acquire an accurate heading. This is possible in static and dynamic conditions, even at high latitudes.

Reliability
Boreas A70 & A90 has been designed from the ground up for rugged reliability. Both the hardware and software are tested and certified to environmental and electromagnetic standards (MIL-STD 461 and MIL-STD 810H). The precision aluminum enclosure is waterproof and dustproof to the IP67 standard. The system is resilient to shock and vibration, allowing it to be used in extreme conditions.

Industry-Leading SWaP-C
The Boreas FOG Series delivers industry-leading performance with a lightweight design, excelling in terms of Size, Weight, Power, and Cost (SWaP-C).

Multi Protocol Support
The Boreas features multiple interfaces, including Ethernet, CAN, RS232, 1PPS, RS422, and GPIOs. It supports industry standard protocols, including NMEA 0183, CANopen, 1PPS, and ANPP, as well as a wide variety of proprietary protocols. A rich, responsive embedded web interface provides full access to all of the device’s internal functions and data. Internal storage allows for up to one year of data logging.
